COMBINATION-PADLOCK.

Application filed November 6, 1907.

T o all 'whom it may concern:

Be it known that I, JosIAH J. DEAL', a citi- Zen of the United States,residing at Canton, in the county of Stark and State of Ohio, haveinvented certain new and usel`ul Improvements in Oombination-Padlocks;and I do hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accom anyingdrawing, making a part oi this speci'iication, and to the numerals andfigures of reference marked thereon, in which- Figure 1 is a perspectiveview of the lock showing the shackle in locked position. Fig. 2 is aview showing the shackle and one oi' the locking disks in relativeposition when the locking disk is held against rotation.

Fig. 3 is a sectional View of the lock body or casing. Fig. 4 is asection showing the different arts properly arranged and the shackleocked. Fig. 5 is a section showing the different parts properly arrangedand the shackle released. Fig. (i is a top view ol the lock body oreasing. Fig. 7 is a section on line 7-7, Fig. 4. Fig. S is a transversesection on line 8 8, Fig. 5. Fig. 9 is a detached view ol one of thecomputing rings. Fig. 10, is a detached view of one of the lockingdisks. Fig. 11 is a perspective view of the lock body or casing. Fig. 12is a detached view of one of the springs.

The present invention has relation to combination pad locks and itconsists in the novel arrangement hereinafter described and particularlypointed out in the claims.

Similar numerals of reference indicate corresponding parts in all thefigures of the drawing.

In the accom anying drawing, 1 represents the lock bor y or what mightbe termed the inner casing, which body is substantially of the formshown in Fig. 11 and as shown it is provided with a series of slots 2and recesses or chambers 3, said recesses being formed of a de th lessthan the thickness of the shell constituting lthe body of the lock, bywhich construction a sufficient amount of metal is provided toconstitute an integral shell or body. Vithin the recesses or chambers 3are located the springs 4, which springs are curved as illustrated inthe draw, ings, and the ends of said springs come in contact with theshoulders 5, when said springs are depressed or forced toward the backsof the chambers 31 The springs are depressed by reason of the ribs 6coming in Specification of Letters Patent.

contact with the inner peripheries oi the various computing rings 7.

The rings 7 are placed upon the body 1 as best illustrated in l* ig. 1and are held in position by means of the end plates S and9. The endplate 8 is preferably formed integral with the lock body or shell 1 andthe opposite end plate 9 held against displacement by means of the rodor bar 10, said bar 10 being connected to the plate 9 in any convenientand well known manner and may be formed integral with the plate S 'ifdesired or may be madeseparate and attached. Upon the rod or bar 10 arelocated a series el locking disks 11, which llocking disks are held inproper spaced relationship with reference to each other, by reason ofthe vflanges 12. At one side of the locking disks 11 is located theshackle-bar 13, which shackle-bai' is provided with the notches 14,which notches are spaced to correspond with the spaced locking disks-11, and when the shackle 15 is seated in the aperture 16 as illustratedin Fig. 4, the shackle and its integral bar will be held againstmovement at all times, except when all of the master notches 17 lormedin the locking disks 11 are brought into alinement with the notches 14.The locking disks 1.1 are rovided with a series of notches 1S, whicnotches are for the purpose of engaging the inner4 ends of the variouspins 19, which pins are secured to the computing rings 7, and when therings are rotated the pins 19 will rotate the locking disks 11. The pins19 secured to the rings 7 are located through the slots 2 and when therings are rotated the given pin will come in contact with the end of thegiven slot 2, and the ring held against rotation in one direction, butfree to move in the opposite direction until the given pin is engaged orbrought into contact with the shoulder at the opposite end of the slot 2or in other words the rings can move only a distance equal to the lengthof the slots 2. Each pin 19 may be set in a diil'erent notch or recess1S. In use the locking disks 11 are all brought into the position so asto bring the master notches 17 into alinement with reference to the bar13, at which time the bar can be moved endwise and then turned, said barbeing limited as to its endwise movement by reason of the head 20, whichhead strikes against the plate S, In use said head should be detachablyconnected by means of the screw 21 so that the parts can be properlyassembled. When it is desired to bring the disks 11 in position to lockthe shackle and its integral bar against movement, the various rings 7are rotated so as to hold the master notches 17 out of alinement withthe shackle-bar 13, at which time there can be no end movement, owing tothe fact that a portion of `each locking disk will be seated in thenotches 14.

For the purpose of producing a clicking movement soas to count thecombination the notches 22 are provided, which notches are yformed onthe inner peripheries of the rings 7, and when said notches pass overthe ribs 6 a clicking is produced. lt will be understood that in orderto commence the counting of a'given combination the computing rings 7will be moved into the proper position with reference to theirparticular combination, and in order to do this the pins 19 must be setagainst the ends of the slots 2.

For the purpose of providing a means for assembling the variouscomputing rings 7 as illustrated in Fig. 1 the body or casing 1 isprovided with the opening or what might be termed the passage ways 23,which passage way permits the pins to move with the computing ringduring theY time the parts are assembled. It will be understood thatwhen it is desired to change the combination the various rings can bedetached when the plate 9 is removed.

For the purpose of holding the locking disks against rotation eachlocking disk is provided with the recesses 24, into which recesses thelower Walls of the notches 14 are set and before there .can be anyrotation of the locking disks 11 the walls of the notches 14 must bedisengaged from the recesses 24, and in order to do this the body of thelock is lifted up when it is suspended or the outer end of the shackleabutted against some object, by which a slight end movement is given tothe shackle-bar 13, after which the locking disk can be rotated.

Having fully described my invention what I claim as new and desire tosecure by Letters Patent, is-

1. In a combination pad-lock, the combination of an inner casing, aseries of rings rotatably mounted upon the casing, said casing providedwith a series of chambers and slots, pins secured to the rings, lockingdisks provided with a series of notches and masternotches, a shackle baradapted to move endwise when released, said shackle bar provided with aseries of notches,
